* Bugfix addressing infinite loop while handling self-referencing chained exception in TestResult._clean_tracebacks()
* Bugfix extended to properly handle exception cycles in _clean_tracebacks. The "seen" set follows the approach used in the TracebackException class (thank you @iritkatriel for pointing it out)
* adds a test for a single chained exception that holds a self-loop in its __cause__ and __context__ attributes
builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.
* Add API to allow extensions to set callback function on creation and destruction of PyCodeObject

Convert macros to static inline functions to avoid macro pitfalls,
like duplication of side effects:
* _PyObject_SIZE()
* _PyObject_VAR_SIZE()
The result type is size_t (unsigned).
The implementation of __sizeof__() methods using _PyObject_SIZE() now
use an unsigned type (size_t) to compute the size, rather than a signed
type (Py_ssize_t).
Cast explicitly signed (Py_ssize_t) values to unsigned type
(Py_ssize_t).
* code_sizeof() now uses an unsigned type (size_t) to compute the result.
* Fix _PyObject_ComputedDictPointer(): cast _PyObject_VAR_SIZE() to
Py_ssize_t, rather than long: it's a different type on 64-bit Windows.
* Clarify that _PyObject_VAR_SIZE() uses an unsigned type (size_t).
* Change _PyDict_KeysSize() and shared_keys_usable_size() return type
from signed (Py_ssize_t) to unsigned (size_t) type.
* new_values() argument type is now unsigned (size_t).
* init_inline_values() now uses size_t rather than int for the 'i'
iterator variable.
* type.__sizeof__() implementation now uses unsigned (size_t) type.
* Fix substitution of TypeVarTuple and ParamSpec together in user generics.
* Fix substitution of ParamSpec followed by TypeVarTuple in generic aliases.
* Check the number of arguments in substitution in user generics containing a
TypeVarTuple and one or more TypeVar.
The following macros are modified to use _Py_RVALUE(), so they can no
longer be used as l-value:
* DK_LOG_SIZE()
* _PyCode_CODE()
* _PyList_ITEMS()
* _PyTuple_ITEMS()
* _Py_SLIST_HEAD()
* _Py_SLIST_ITEM_NEXT()
_PyCode_CODE() is private and other macros are part of the internal
C API.
Convert macros to static inline functions to avoid macro pitfalls,
like duplication of side effects:
* DK_ENTRIES()
* DK_UNICODE_ENTRIES()
* PyCode_GetNumFree()
* PyFloat_AS_DOUBLE()
* PyInstanceMethod_GET_FUNCTION()
* PyMemoryView_GET_BASE()
* PyMemoryView_GET_BUFFER()
* PyMethod_GET_FUNCTION()
* PyMethod_GET_SELF()
* PySet_GET_SIZE()
* _PyHeapType_GET_MEMBERS()
Changes:
* PyCode_GetNumFree() casts PyCode_GetNumFree.co_nfreevars from int
to Py_ssize_t to be future proof, and because Py_ssize_t is
commonly used in the C API.
* PyCode_GetNumFree() doesn't cast its argument: the replaced macro
already required the exact type PyCodeObject*.
* Add assertions in some functions using "CAST" macros to check
the arguments type when Python is built with assertions
(debug build).
* Remove an outdated comment in unicodeobject.h.
These slots are marked "should be treated as read-only" in the
table at the start of the document. That doesn't say anything about
setting them in the static struct.
`tp_bases` docs did say that it should be ``NULL`` (TIL!). If you
ignore that, seemingly nothing bad happens. However, some slots
may not be inherited, depending on which sub-slot structs are present.
(FWIW, NumPy sets tp_bases and is affected by the quirk -- though to
be fair, its DUAL_INHERIT code probably predates tp_bases docs, and
also the result happens to be benign.)
This patch makes things explicit.
It also makes the summary table legend easier to scan.
